SPECIFICATION forming part of Letters Patent No. 455,608, dated July '7, 1891. I

Application filed November 10, 1890. Serial No. 370,933- (No model.)

To aZZ- whom it nuty concern:

Be it known that I, LEMUEL COB URN, a citizen of the United States, residing at Holstitute a housing for the trackway and rollers therein.

The invention consists in certain formations of the parts and the novel combination and arrangement thereof, all substantially as will hereinafter more fully appear and be set forth in the claims. v

In the accompanying drawings, Figure 1 is a view in elevation and partial section of the side wall of a car-door or other structure with the trolley-supports for the door applied there on, while Fig. 2 is a vertical cross-section of the same. The sectional portion of Fig. 1 is taken on the plane 1 2 of Fig. 2. Fig.3 is a view of a portion of the hanger.

In the drawings, a indicates the heading, secured upon but oifset from the side of the wall b above the doorway and from which the trolley-track A is. supported. I The trolley-track consists of the supporting portion (1 and a pair of united troughs f and f, arranged in a horizontal plane, and in the m anufacture all are integrally formed from sheet metal, the portion d being as a continuation of but usually angularly from one of the troughs. The supporting portion d is secured on the heading 0 and pends therefrom, so that the troughs are located at a suitable distance from and under and parallel with the lower edge of the heading. In the pre ferred form of the trolley-track, and as shown in the drawings, a portion ofthe sheet or thin metal uniting the troughways is in the form of a corrugation, as at g, and said troughways at each side thereof are in transverse section rounded or more or less nearly of semicircular form, thereby forming efficient horizontaland longitudinal supports for the rollers jj, united by the axle or pintle k, and also forming for said rollers guards, whereby they are constrained against movement transversely of the run of the track.

The hanger B consists of the continuous straight-edged portion Z, adapted to be ranged longitudinally and supported upon the axles of two or more of the paired rollers, the pending portion m separated from the portion Z,

,,and at the other side of the track from that occupied by the track-supporting portion d, being extended downwardly below the level of the track and the arch-like uniting portion at, which overlies one ofthe rollers j. The door 19 is bolted or otherwise supported upon the hanger, and it will be seen that the trackway and the paired rollers and the bearing portion Z of the hanger are compactly housed in and protected from the weather and dust or dirt, the freedom of operation, nevertheless, being in no way impaired. As the door is slid the hanger B, running or rollingover the axles of the paired rollers,

and the rollers themselves also having a progressive movement in the direction that the door is moved, it is desirable to provide stops at the ends of the trolley-trackfor instance, as indicated-at q-whereby the rolls may not under any circumstances be permitted to escape at the ends of the track, and also to provide stops, as indicated at t, whereby the roll- 2. The combination, with a wall or support provided with a heading, of a trolleytl'aok comprising a hanging Wall supported from said heading and the inwardly-turned troughway-forming portion, double and pintle-united rollers movable in the traokway, the hanger consisting of the longitudinal portion Z, the continuous arched section 02, and a pending portion m, substantially as and for the purpose set forth.
